Get out there! You need a helmet and gloves to start. You can buy bike shorts and adjust your saddle as your distance increases. Don't set any goals for the first ride except to scout everything out. That way if it doesn't go perfect, you won't be disappointed. Add small goals: ride a few extra miles, find bike shorts, learn to add air to your tires, learn how to change a tire, go farther up that hill. Only by trying a few different bikes, will you decide what you prefer. Like a stray cat, my road bike picked me
